目前现行的农作物品种区域试验方法,多采用多重比较设计,新复极差(方差)分析方法,该方法始于误差分析理论,在一定的概率水平上采用,只是对单个性状进行互作效应的评定。作出定性的描述,在农作物品种区域试验汇总结果分析中无法对多个各类性状进行定量分析和综合评价。多年来用单一产量增产百分比来评定品种,弊病很多,不能从品种的丰产性、稳产性、适应性、抗逆性、抗病性和品质性状等诸多性状上综合评价品种的使用价值,重产量轻品质,结果是
At present, the current regional trial methods of crop varieties use multiple comparison design and new method of analysis of variance (variance). This method originated from the theory of error analysis and is adopted at a certain probability level, only for the interaction of individual traits assessment. Make a qualitative description, can not quantitatively analyze and comprehensively evaluate a plurality of various traits in the summary analysis of crop variety regional trials. Over the years with a single yield increase to assess the percentage of varieties, many drawbacks, can not be from the variety of high yield, stability, adaptability, resistance, disease resistance and quality traits and many other traits comprehensive evaluation of the value of the variety, the yield Light quality, the result is
